Neuron_Reduce – a brand new tool to simplify complex neuron models

— Detailed neuron models consisting of thousands of synapses are key for understanding the computational properties of single neurons and large neuronal networks, and for interpreting experimental results. Simulations of these models are however, computationally expensive (using lots of computing hours), which considerably decreases their utility. For the first time, Scientists at the Hebrew University of Jerusalem and the EPFL Blue Brain Project have formulated a unique analytical approach to the challenge of reducing the complexity of neuron models while retaining their key input/output functions and their computational capabilities. ‘Neuron_Reduce’ is a new computational tool that provides the scientific community with a straightforward capability to simplify complex neuron models of any cell type and still faithfully preserve its input-output properties while significantly reducing simulation run-time.

Simulating Biophysical Principles of Functional Synaptic Plasticity in the Neocortex – INCITE grant renewed for 2018

A team of scientists led by Eilif Muller of the Blue Brain Project, have had their INCITE grant renewed for 2018 to provide a further 160 million core hours at the Argonne National Laboratory. INCITE supports computationally intensive, large-scale research projects with large amounts of dedicated time on supercomputers at DOE’s Leadership Computing Facilities. In 2017, INCITE awarded the Blue Brain with 100 million core hours to simulate biophysical synaptic plasticity in reconstructions of the neocortical microcircuit to discover their synergistic functional principles.

During our lifetimes, our brains undergo continuous changes as a consequence of our experiences. Synaptic plasticity—the biological process by which brain activity leads to changes in synaptic connections, is thought to be central to learning and memory. However, little is known about how this process shapes biological neural networks.

With this renewed grant, the team that also includes scientists from the École polytechnique fédérale de Lausanne and The Hebrew University of Jerusalem will continue to focus on advancing our understanding of these fundamental mechanisms of the brain’s neocortex. The team is carrying out large-scale simulations of recently uncovered biophysical principles underlying synaptic plasticity in reconstructions of a neocortical microcircuit (Markram et al., 2015; 10.1016/j.cell.2015.09.029) consisting of around 200,000 neurons and 260 million synapses. The aim is to shed light on the synergistic functional principles that shape plasticity in realistic cortical circuits.

The team is also using DOE supercomputers to characterize: (1) the role of NMDA receptor spikes in plasticity induction; (2) the dynamics of neuronal assembly formation and maintenance; and (3) the computational impact of synaptic plasticity in common signal processing tasks. In addition to improving our understanding of the brain, this research could help inform the development of enhanced deep learning methods, as well as new learning paradigms for neuromorphic hardware.

Successful Neuromodulation of Neural Microcircuits NM² Conference prompts future collaborations

At the end of September, the Blue Brain Project concluded a stimulating, interactive and highly collaborative Neuromodulation of Neural Microcircuits NM² Conference. A global line-up of renowned speakers and more than one hundred attendees from across the different Neuromodulation communities ensured a cross-pollination of experience and expertise throughout the three-day Conference.

Neuromodulators – the master switches – dynamically reconfigure neural microcircuits and shape brain states by controlling the function of neurons and glia, dendrites, and synapses. Recently, the Blue Brain Project discovered that neocortical microcircuit activity shifts from synchronous to asynchronous network states that is tightly controlled by neuronal and synaptic physiology. This effect is strikingly similar to the function of neuromodulators, which control neurons and synapses to sculpt the emergence of brain states.

Therefore, understanding the mechanisms by which neuromodulators operate is not only fundamental to Blue Brain’s pioneering work in simulating brain function and dysfunction, but also the global neuroscience community. Over the three days of the Conference, 34 leading experts in this field presented their current research and enthusiastically participated in panel discussions, as both speakers and participants took part in shaping the future course of neuromodulatory research. Srikanth Ramaswamy, NM² Conference Host said “This meeting is unique in that it focuses on the mechanisms by which diverse neuromodulators could give rise to similar behavioral states by differentially controlling neuronal and synaptic activity.”

With a strategic focus on the neuromodulation of microcircuits, the Conference provided a platform to identify common principles by which different neuromodulators regulate the activity of neurons and glia, dendrites, and synapses. Speaker and day three Chair Randy Bruno said “Biologists have been listening to the raucous activity of neural circuits for a century. Only recently have we begun to appreciate how neuromodulation quietly orchestrates it all”.

The successful NM2 Conference has not only provided a springboard to shape a follow-up event in 2019, but has also laid the foundation towards an international consortium to drive collaborative research in neuromodulation.

Further information on the 2019 Conference will be published on and

A Topological Representation of Branching Neuronal Morphologies

In a paper published in the journal Neuroinformatics, a team of scientists led by the Blue Brain Project, in collaboration with the Laboratory for Topology and Neuroscience, explain how the invention of the Topological Morphology Descriptor (TMD), provides a method for encoding the spatial structure of any tree as a “barcode”, a unique topological signature.

Many biological systems consist of branching structures that exhibit a wide variety of shapes. Understanding of their systematic roles is hampered from the start by the lack of a fundamental means of standardizing the description of complex branching patterns, such as those of neuronal trees.

As opposed to traditional morphometrics, the TMD couples the topology of the branches with their spatial extents by tracking their topological evolution in 3-dimensional space. The team prove that neuronal trees, as well as stochastically generated trees, can be accurately categorized based on their TMD profiles.

The TMD retains sufficient global and local information to create an unbiased benchmark test for their categorization and is able to quantify and characterize the structural differences between distinct morphological groups. The use of this mathematically rigorous method will advance our understanding of the anatomy and diversity of branching morphologies.

Comprehensive Morpho-Electrotonic Analysis Shows two Distinct Classes of L2 and L3 Pyramidal Neurons in Human Temporal Cortex

The group of Idan Segev of the Hebrew University of Jerusalem and Christiaan P.J. de Kock of the Vrije Universiteit, Amsterdam, in collaboration with the Molecular Systems Section in the Simulation Neuroscience Division of the Blue Brain Project, employed feature-based statistical methods, on a rare data set of 60 3D reconstructed pyramidal neurons from L2 and L3 in the human temporal cortex (HL2/L3 PCs) removed after brain surgery.

Of these cells, 25 neurons were also characterized physiologically. Thirty-two morphological features were analyzed, 18 of which showed a significant gradual increase with depth from the pia (e.g., dendritic length and soma radius). The other features showed weak or no correlation with depth (e.g., dendritic diameter).

The basal dendritic terminals in HL2/L3 PCs are particularly elongated, enabling multiple nonlinear processing units in these dendrites. Unlike the morphological features, the active biophysical features (e.g., spike shapes and rates) and passive/cable features (e.g., somatic input resistance, membrane time constant, and dendritic cable length) appear to be depth-independent.

A novel topological descriptor for apical dendrites yielded two distinct classes, termed hereby as “slim-tufted” and “profuse-tufted” HL2/L3 PCs. The two classes also differ in their electrical properties, as the “profuse-tufted” cells tend to fire at higher rates. Therefore, two distinct morpho-electrotonic classes of HL2/L3 Pcs were identified for the first time.
